Adjustable mounting device

ABSTRACT

An adjustable mounting device for a cutting tool is described. The device is comprised of elements which are angularly adjustable about orthogonal axes which intersect at a common point. The tip of the cutting tool is mounted in the device to substantially coincide with the common point of intersection so that the position of the tip remains substantially stationary when angular adjustments are made.

It is well known to rnountcutting tools to allow for various angular adjustments ofthe tool's cutting tip-in relationship-to a surface being scored or-cut; For example, afiball and socket.

In the case of glasscutting it is-often-desired to adjust: the cuttingtip to an optimum angular positionr'elativetol the glass, especially when the tipg's, configuration is modified.- by wear; While the Anotherobject: of-the invention is; to provide a-.de.vice for mounting. a cutting tool for-angular adjustmenraboutthree.

Mountedion the slide block 3 is a holder block 10. Holder block 10 includes a ferrule for holding a-cutting tool 11 and forms the'top half of the slide arrangement which permits the adjustment 6 in a plane perpendicular to the direction of cut of the cutting tool l l' cutting tool 1!, with a diamond tip P. is

locked in the holderblock' l0by means of setscrew 12. Setjustable mounting device. can be fabricated from suitable materials such as metal orplastic.

When it is desired to adjust the diamond tip P to an optirnu m angular relationship with a glass plate G, the tip P remains substantially stationary and the various elements of the .'mounting device are moved to the desir'edangular setting about'orthogonal axes whichpass through tip P. For example, if it isdesired to adjust the diamond tip P about the longitudinal axis of the cuttingtool, then setscrew 12 is loosened and the adjustment is made by rotating the tool. To adjust the diamond tip P for an 0- angle a in a plane parallel to the direction of'cut, setscrew 9is loosened and the adjustment is made by turning pinion gear 6 which causes slide block 3 to move. If it is desired to adjust the diamondtip P for an angle 9 in a plane perpendicular to the direction of cut. then setscrews l3 are. loosenedand thea'djustment is made by moving the holding block 10. While the axes of a preferred embodiment are orthogonal it should be. understood that the desired adjustments couldbe made about axes intersecting at different angles.

From the above; it should be appreciated that all three adjustments can be accomplished independently of one another. This' independence results' from the fact that the tip P coincides with the axes ofangularmovement for the cutting tool 11; the holder-block l0, and the slide block 3. independent adjustment enablesan operator to quickly and precisely adjust themounting device.

it should also be appreciated that the adjustable mounting device of the. present invention can be utilized in other fields oftechnology. For example, if used as a microscope stage, the mounting device wouldallow the examination of several sides of an objectwithout removing it from the field of view. When used in this manner, a point locatedon the outer surface of the tain. alignment of the.pinion 6-withthe rack t This -arrange-- ment allows theusrto makewaefifne adjustment in-theangular.

object would substantially coincide with the common point of intersection ofthe axesabout which adjustment of the object is accomplished. The surface point could be at a surface discontinuity, such as the apex of a cone, or could be a location on a continuous surface. The mounting device could also 55 be utilized to set and holda metal working tool at a compound angle for grinding. Other uses of the adjustable mounting device of the: present invention will" be apparent to those skilled in theart.

The: invention has-been described in detail with particular reference to preferred'enibodiments thereof, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention as described hereinabove and as defined in the appended claims.
